Alright after about 24 hours - These are my thoughts about the S6edge+
Overall, its not bad. Android is definitely the bottleneck of the device. With that being said, I have noticed major issues with touch screen sensitivity and recognition. I have to click the same spots 3-4 times for the screen to respond, and I need to swipe down from the top 2-3 times for it to work at all. Extremely annoying.
Device is constantly hot, both when charging and when not charging, with minimal usage.
Screen is absolutely gorgeous.. Indoors. As soon as you take it outside, it is completely washed out. Colors are a bit over saturated, but its extremely vibrant.
Phone is a little large for me personally. The main reason why I did this was to see if I want a 6s+ or just a 6s. I feel the 6s is a good size for me. The bigger screen is nice, but it is a hassle to carry around.
Edge display is kind of gimmicky. I do like the nighttime mode with the time, temp and power level on the side of the screen. Very easy to look at, but other than that I see no use of the edge.
For being a high-grade material phone, it feels really cheap. I don't know if its because the back is the world's thinnest glass and thats what I'm touching the majority of the time, or if its the thinness, but I feel like I could snap it.
Battery life isn't that great. I know I have been using it a lot, but I got about 7 hours of usage yesterday. I can easily pull 8 hours on my iPhone 6 running iOS9. I know the Samsung has a larger screen, but its battery is almost twice the size as the iPhone 6.
Camera is absolute crap IMO. I took plenty of test shots between the Samsung and my iPhone 6. The Samsung's photos are more vibrant and more colorful without a doubt, but as soon as you start to zoom in, its blurry. iPhone on the other hand, wasn't blurry at all. I took about 10 photos with each device, and it was the same result every single time. I don't know if its a faulty camera, but this 16MP camera makes my 8MP camera look amazing.
Overall, by no means would I ever make the switch, but it was nice getting to use Samsung/Android. I constantly rag on it, and its not as bad as what I expected (its been completely updated), but nothing compared to my iPhone. My screen is responsive, doesn't run hot and battery is much better.
